# Maths KS2: Understanding area and perimeter

The Grecian pizza parlour boss brings up from the cellar a box of 80 ‘smashing plates’ that must be arranged in piles three deep around the perimeter of the restaurant.

The guests will smash them at the end of the pizza party after the dancing.

Apprentice Ambrose’s boss explains the difference between area and perimeter.

Perimeter is ‘the distance round the outside edge’ and area is the ‘space inside’.

Ambrose must work out how many plates he needs and how many boxes to fetch.

Ambrose also learns the quick way of finding the perimeter of a rectangle as (2 x length) + (2 x width).

He measures the restaurant in plates.

Three questions of increasing difficulty are asked about area and perimeter based on the pizza parlour scenario.

### Teacher Notes

There are three differentiated questions based on the scenario to be solved as a whole class or as individuals.

The questions build from one step to multi-step word problems.
